If you want light, durable and modern then unfortunately you're going to struggle finding a new 80mm air fork with untapered steerer and canti/V brake mountings. No one seems to make sub 1500g with canti/V mounts anymore (?). Magura Durins were made until a couple of years ago but even they only make disc versions now. You'll probably have to go for a decent second hand fork. Marzocchi Bomber / Rockshox SID / Magura Durin / Pace etc.
